Eric Feldt — joined the first intake of the Royal Australian Naval College in 1913. He left the Navy to serve as a district officer in New Guinea, and it was those years in the islands that made him the right man for the job: he knew the archipelago, and he knew the people who lived in it. He was called back in 1939 to command the Coastwatchers.

The radio — every station carried an AWA Teleradio 3B, a set designed for Australia's outback flying doctor service. With its battery and charging motor it weighed over 100 kg, and moving a station took 12 to 16 carriers. Going quiet was rarely carelessness.

Ferdinand — the world knew them as the Coastwatchers, but among themselves the network had another name. Feldt christened it Ferdinand, after the bull in the children's book who would rather smell flowers than fight, made famous by a Disney short in 1938. It was not a joke: it was the order, put in a way nobody would forget. Men alone behind Japanese lines, an enemy fleet steaming past, and the instruction was to do nothing — only watch, and tell. Observe and report, never intervene. It was enough: a raid called in two hours ahead was a squadron already in the air. Halsey put it plainly afterwards — the Coastwatchers saved Guadalcanal, and Guadalcanal saved the South Pacific.

Here — each ferdinand watches a single machine: one server, virtual or physical. In Kubernetes that machine is called a node, and it is where the applications run; outside a cluster it is an ordinary VM — and this fleet has one. It does not remediate, it does not interfere: its whole value is the head start the warning gives to whoever can act. The feldt keeps the board and notices who stopped transmitting. Silence is the alarm.
